PORTLAND MUSEUM OF ART | For some years now, Anna Hepler has been creating woodcuts and wire sculptures of floating ball-like nests. "Makeshift" (July 24 through October 17) may be her most ambitious project yet as the Maine artist fills the museum's Great Hall with a "nest-like mesh of salvaged and sewn plastic." Also on view are watercolors by Winslow Homer (through September 6) and "American Moderns" (through September 12), featuring works on paper by Edward Hopper, John Marin, Rockwell Kent, Georgia O'Keeffe, Andrew Wyeth, and more.

NEW HAMPSHIRECURRIER MUSEUM OF ART | "Jerome Liebling: Capturing the Human Spirit" (June 19 through September 19) explores the Amherst resident's documentary photos of New Yorkers, a Minnesota slaughterhouse, and farming in Massachusetts's Pioneer Valley. The images are rich, like the work of his teacher Paul Strand, but also gritty. He aims, he's said, to "figure out where the pain was." Also on view through September 6 are Ipswich, Massachusetts, sculptor George Sherwood's shimmering, gliding stainless-steel whirligigs.
